Question about 2006 Hummer H3
My h3 sometimes does't want to start, Disconnect battery and hook right back and then it starts, next, open passengers door and the interior lights didn't go on, went drivers side they went on, tried to start would not start, disconnect battery, hooked back up and it started, then it read on dashboard, door open, all doors were closed... must be a bad switch??
My H3 didn't start this morning. I noticed something unusual about my truck when I first tried. The alarm had a weak sound when it went off. The fact that it turned over but didn't start made me believe it was not the battery. I was trying to call the mechanic and a wrecker to get my H3 fixed. However, before that I got the wrecker out there, I went to Autozone. He told me it sounded like the battery and cold weather kills the battery. So 3 hours have passed and temperatures warmed up to a cool 56 degrees. I was going to put jumper cables but out of curiousity, I said well let me crank it and see if it was cold weather. Sure enough, it cranked right up.
Either way, I am going to take it to Autozone and have the battery checked. I can't miss another day of work due to an old battery.

My 2006 H3 60k miler is doing the same thing. Started about a year ago and has become more frequent over time (and maybe miles). Like others, I have tried to diagnois the problem and have found only one common denominator - do nothing but wait 20 minutes and the vehicle will start as normal. I checked with another local owner and his 2006 H3 is doing likewise - only difference is that he has less miles and less frequent start failues. My internet search has turned up phantom causes of sticking valves, ignition switch and seat movement. Sure hope to find the cause as I truely love the H3.
